Description

The WVM Series provides protection against premature

equipment (motor) failure caused by voltage faults on the

3-phase line. The WVM’s microcontroller design provides reliable

protection even if regenerated voltages are present. It combines

dependable fault sensing with a 10 fault memory and a 6 LED

status display. Part instrument, part control, the WVM protects

your equipment when you’re not there and displays what

happened when you return. The WVM is fully adjustable and

includes time delays to prevent nuisance tripping and improve

system operation. Time delays include a 0.25 to 30s adjustable

trip delay, an adjustable 0.25 to 64m (in 3 ranges) restart delay,

plus a unique 3 to 15s true random start delay. The random start

delay prevents voltage sags caused by simultaneous restarting

of numerous motor loads after a power outage.
